An electron in an oscilloscope tube is traveling horizontally with a speed of 4.1×106m/s . It passes through a 2.0cm long region with an electric field pointing upward by a magnitude of 1700N/C .
1. What is the magnitude of the electron’s velocity when it emerges from the electric field region?
2. What is the direction of the electron’s velocity when it emerges from the electric field region?
